Answer:
radius = 30 in
Step-by-step explanation:
EF = circumference × fraction of circle, substitute values
5π = 2πr ×
← where r is the radius
5π = 2πr × 
Multiply both sides by 12 to clear the fraction
60π = 2πr ( divide both sides by 2π )
= r, thus
r = 30 in
Answer:
63
Step-by-step explanation:
In these 9 bags, each must have 7 gumdrops. So, we can add 7 nine times to itself. 7 + 7 + 7 + 7 + ... = 63
OR HERE'S A FASTER WAY *WINK WINK*
Instead of doing repeated addition, we can <u>multiply</u> 7 and 9 together.
<u>Why multiply?</u>
We're going to multiply 7 x 9 so that it means seven gumdrops for <em>each</em> of nine bags.
7 x 9 = 63.
